Salam Alaikum dear Sisters,🌸
I hope you are all doing well.
A warm welcome to our new sisters joining the group. I hope you will find valuable information and sisters here that inspires and supports your personal growth. ❤️
Today is Thursday, and I’m continuing messages about our bodies.
Today one of most important micronutrients for thyroid health: SELENIUM. If you remember, I’ve already texted about the thyroid from a psychological and psychosomatic side. Now I want to share the nutritional side, because in my holistic consultations I’m seeing more and more cases where selenium deficiency is directly affecting thyroid balance.
Selenium is essential for converting the T4 hormone (whether naturally produced or taken as L-thyroxine) into active T3. This conversion is done by enzymes called deiodinases (DIO1 and DIO2), all of which are selenoproteins. Without selenium, this process simply does not happen.
Even if your blood tests show thyroid hormones “in range,” a lack of selenium can leave you with hypothyroid symptoms like:
• Fatigue and weakness
• Cold intolerance
• Slow metabolism
• Hair loss
• Dry, dull skin
• Slow wound healing
• Weak immunity
Many people are low in selenium because of modern farming. It has depleted selenium in soil, reducing levels in fruits, vegetables, and grains. Also highly processed foods strip away selenium naturally found in whole foods. People having more digestive issues, gut inflammation, or poor absorption.
We women need it more. Pregnancy, breastfeeding, and chronic illness increase the body’s selenium.
Selenium benefits
🔸 Reduces antibodies in autoimmune thyroiditis (AIT) and Graves’ disease.
🔸 Lowers oxidative stress and inflammation.
🔸 Acts as an antioxidant for heart and blood vessel health.
🔸 Supports mood, memory, and concentration.
🔸 Improves fertility (sperm and egg quality). Those who trying to conceive must take selenium.
🔸 Aids glutathione production -your body’s master antioxidant.
🔸 Helps remove heavy metals, especially mercury.
Natural food is always the best source of selenium, just remember: selenium content in plant foods varies depending on the soil where they’re grown.
Include in your meals Brazil nuts (just 1–2 can meet daily needs), sardines, mackerel, wild salmon, prawns, crab, beef, lamb, chicken, turkey, eggs (especially the yolk), brown rice, oats, whole wheat.
If you need supplements note, not all forms are safe or effective.
Best forms for absorption:
✔️ Selenomethionine
✔️ Selenocysteine
❌ Avoid sodium selenite
If symptoms are present I recommend to take it minimum 3–6 months with monitoring, at 100–200 mcg per day. For long-term use if you have autoimmune thyroiditis, follow endocrinologist advices and lab results to avoid toxicity.
I’m personally a strong believer in functional norms. Very often, when blood test results show “normal” ranges, it doesn’t necessarily mean everything is truly optimal, especially if you’re having symptoms. Functional ranges focus on what’s ideal for your body’s best performance, not just what avoids disease.
Even if your blood levels look “normal” according to laboratory ranges but they are on the lower side or borderline, it can mean that without enough selenium your body can’t fully use certain nutrients, including:
• Iodine
• Vitamin E
• Zinc
• Iron
• Coenzyme Q10
• Glutathione
I’ve also shared how to understand the difference between functional optimal norms and the laboratory reference ranges provided by labs. Knowing this is important for everyone, as it can make a real difference in spotting imbalances early and taking action before they become serious.
Note for sisters in the UK:
The NHS does not routinely check selenium levels when testing thyroid function. If you have ongoing symptoms, you may need private testing, holistic guidance, or you can personally request selenium testing from your GP.
Wishing you all good health, balance, and the knowledge to care for your bodies every day. ☀️
